Abstract
A whispering gallery mode dielectric resonator includes a conductive enclosure comprising a top, a bottom and walls. The resonator also includes a dielectric element disposed in the enclosure and operative to support a desired resonant mode that is dependent on a shape and dimensions of the dielectric resonator; and a mode selective coupling structure disposed over the enclosure and configured to selectively couple electromagnetic energy of the desired mode and configured not to substantially couple electromagnetic energy of a spurious mode supported in a region between the enclosure and the dielectric element.
